- Application filed April i1, 1917 Serial- No. 161 .,228.

' To all whom it may-concern:

- I Beit known'that I, Dwrerrr T. RA -nALn, a citizen of the United States, and resident of Detroit, Wayne county, State of Michi- This invention relates tohydrocarbon motors, and particularly to improvements in cooling systems especially adapted for use therewithQ One of the objects of this. invention is to provide an internal combustion engine with a cooling system having adequate means for condensing and conservingany vapors which are formed'by the cooling liquid.

The motor vehicle power plant,'whic h is generally used, is provided with no-ad'equate means for preventing loss of the'motor cool;

ing" fluid either when the level rises above a predetermlned point or when'the. temperature becomes so high that th'eliquid is vapor- -ized. l/Vith such installations, "when the mo- 1 tor is operating under high temperature conditions, the operator is subjected to the burden and annoyance of frequent replenish ment of the cooling liquid. Such: a condition results in considerable expense when costly anti-freeze solutions are-used.

To overcome these and other objections, I have provided adequate means for prevents ing the loss of any of the cooling fluid from the system, either in a vapor or liquid state.

. In "general, my invention comprises a'c'ondenser connected with a-circulating system at a point abovethe normal level of the liquid withinvt he cooling system, and so lo cated that it will always be subject to. an adequate cooling action. In my preferred embodiment,the condenser is arranged in line with the radiator and a fan so that air'will be direc'ted over the condense'rbefore passing through saidrad'iatorlf I, Another-object is. to provide an improved condenser'for an internal combustion engine cooling system; i

These'and various other objects will ap-f pearfrom thefollowing description taken in connection withthe' drawing which forms a part of this specificatiom'and in ,which is illustrated aside elevation with portions broken away, "of a .;motor vehicle power plant, embodying a preferred form of my invent1on. Referringito the drawing, 10 represents The cylinder block is provided with the 1 tubes 25 and. 26. respectively.

Q

The radiator13 comprises an upper tank 23, a lower tank 24, and arranged intermedi fate thereof, are, a set of radiating tubes 25 and a set of condensing tubes 26. The upper tank 23 is provided with a filling thimble 2 7, which is adapted be normally; sealed by a cap 28, which is suitably secured in position. It will-be'noted that the upper GIldSlOf the radiatingv and condenser tubes 25 and'26, respectively, are arranged adja-.

'cent'the' lower end 29 of the upper "tank 23 at opposite sides of a suitably secured par tition 30, the upper end of which extends to 'a point above the normal level of the liquid within the circulating. system. It'is also to be noted thata partitional Wall 31 is arranged in the'lower tank 24 between the and condensing lower endsl of the radiating A reservolr or tank 32, provided with a 1 Having described the general construction and arrangement of the various parts, the

operation of a preferred form of my cooling system will be Understood as follows As the temperatureof the cooling mediumrises above the vaporizing point of the cooling liquid, the vapor generated will-be dischargedinto the upper end of the condensing tubes 26, and downwardly therethrough.

@On account of the fact that these tubes are arranged in the front of the fan 14, and the radiator tubes 25, all ofthe air which passes throughthese parts will first cool the condensing tubes 26 and then the radiator tubes then through thepor't-37, conduit 36 and- -25, with the result that any vapor within the tubes 26 will be cooled and thereby condens'ed, then flowing into the lower tank 38,

finally entering through the port 3& to the interior of the tank 32.

It will, of course, be understood that asthe liquid within the circulating system, cools, after having discharged a considerable quantity therefrom through the condenser tubes 26 in the form of a vapor, a partlal vacuumv will be produced in'the system with "the result that the pressure of the atmoshere acting on the tank 32 through the vent 33, will automatically return the discharged liquid from the tank back through the conduit-36 and condensertubes-26, to the upper part of the radiator 13, v t

' It'will, of course, be understood also that in the event the'level of the liquid within the cooling system rises above the predeterfmined normal for any reason, the surplus will flow over nto the condenser andbe con-.

served in'the tank.32. In actual practice, I

refer to retain a small quantity of liquid.

1n the bottom of the tank 32 to serve as a.

condenser in the vent that the cooling effect of the tubes 26 is not-suflicient to reduce th vapor to a liquid state.

' v While I havedescribed and will specifi-- cally claim'what I deem to be a preferred form-of my invention, it, of course, will be obvious to those skilled in the art thatvari one modifications and changes may be made without departing from the spirit and scope hereof. i
